|Other Names||Protein-tyrosine sulfotransferase 1, Tyrosylprotein sulfotransferase 1, TPST-1, TPST1|
|Target/Specificity||The synthetic peptide sequence used to generate the antibody AP2321a was selected from the N-term region of human TPST1. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay.|
|Format||Peptides are lyophilized in a solid powder format. Peptides can be reconstituted in solution using the appropriate buffer as needed.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.|
|Precautions||This product is for research use only. Not for use in diagnostic or therapeutic procedures.|
|Function||Catalyzes the O-sulfation of tyrosine residues within acidic motifs of polypeptides, using 3'-phosphoadenylyl sulfate (PAPS) as cosubstrate.|
|Cellular Location||Golgi apparatus membrane; Single-pass type II membrane protein|
|Tissue Location||Ubiquitous. Detected in heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas|

The importance of tyrosine O-sulfation in protein-protein interactions is illustrated by the sulfation of tyrosine residues in the leukocyte adhesion molecule P-selectin glycoprotein ligand-1; sulfation is required for its binding to P-selectin on activated endothelium. This enzyme represents a new class of Golgi sulfotransferases that catalyze tyrosine O-sulfation of many protein substrates involved in diverse physiologic functions including inflammation, hemostasis, body weight and reproductive physiology.
